Answer:
B sediment
Explanation:
The excess mileage leads to additional pollution. Car exhaust contains toxic gases, and car fluids often leak (oil drips, antifreeze leaks, etc...). The exhaust also contains nitrogen oxide, which can lead to nutrient-related problems in the environment.
C=2.41 g/L
m(NaCl)=0.291 g
c=m(NaCl)/v
v=m(NaCl)/c
v=0.291/2.41= 0.1207 L = 120.7 mL
